how do you know about antares?

it connects with andreev's 'rose of the world' book:

"But the ziggurats in the cities of Babylonia and the collective of initiates who absorbed the radiations of the cosmic powers of Light on top of their mystical observatories were also not shielded from the extremely harmful radiations coming from the galactic anticosmos, whose center in Enrof is located in the Antares system."

" I have already said that bramfaturas in which demons have been victorious are not long-lived, and the large planet revolving around Antares that is presently energizing the Pit of Shadanakar will soon break up, but another will take its place. The one that energized the Pit at the time of Shadanakar's founding perished millions of years ago.
Antares is visible in our latitudes low on the southern horizon in late spring and summer, and many may remember well its brightly pulsating wine-red rays. Neither the sun nor any other heavenly bodies are visible from the Pit of Shadanakar—only motionless Antares, on which one end of the Pit rests. In the Pit, it appears infrared. In the opposite direction, the one-dimensional world fades as it approaches the surface of the Earth."
